I'm green to giving quotes on landscape jobs. I don't know how much I should mark up certain aspects of the job. How much do you add to you material costs? How about labor costs? Just doubling the materials and nilly willying the rest doesn't seem very smart to me and could very well cost me a job when bidding against a savvy quote maker. I know that this question may vary dramatically from person to person but I was wondering if there is a rule of thumb or how you guys price a job out to make sure you don't end up paying the customer to do the job. Any feedback would be appreciated.
